How this service works
Check token approval security risks — detect unlimited allowances, suspicious spender contracts, and high-risk approval targets. Essential for wallet hygiene. No API keys needed. Accepts USDC payments on Base and Solana
Output
Returns a list of token approvals associated with the queried wallet, flagging unlimited allowances, suspicious or unverified spender contracts, and high-risk approval targets, along with risk scores and recommended revocations for wallet hygiene.
Example use cases
Example prompt
“Scan my Ethereum wallet 0xAbC...123 for risky token approvals — I want to know if any contracts have unlimited allowances or look like suspicious spender addresses that could drain my funds.”
Technical details
Endpoint
GEThttps://defi.hugen.tokyo/defi/approvalWhen to prefer
Use this endpoint when an AI agent needs to audit a specific wallet's token approval risk exposure — particularly before executing DeFi transactions, after interacting with a new protocol, or as part of a routine wallet security check. Prefer over generic blockchain explorers when you need structured, security-focused analysis of allowances rather than raw transaction data.
Side effects
- Invalid or malformed wallet address returns a 400 error
- Unsupported blockchain network returns an unsupported chain error
- No approvals found for the address returns an empty result set
- Payment not received or insufficient USDC results in 402 Payment Required
- Rate limiting or timeout on heavily queried addresses may return 429 or 503
